UNITED STATES RAYMOND LARSON, OF DE KALB, ILLINOIS.

CEMENT REENEORCEMENT.

Application filed August 28, 1922. Serial No. 584,853.

To aZZ whom it may concern:

Be it known that I, RAYMOND LARSON, a citizen of the United States, residing at De Kalb, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Cement Reenforcements, of which the following is a specification.

My invention relates to improvements in cement reenforcements.

An object of my invention is to provide a cement reenforcement, that is particularly adapted to be used as a reenforcement in the construction of cement roads.

A further object of my invention is to provide a cement reenforcement, that will prevent cracking, hui'nping and breaking of the cement.

A still further object of my invention is to provide a cement reenforcement, that is so constructed, that a rigid network is built right in the cement, in such a manner, that a cement road is made more practical than heretofore.

A still further object of my invention is to provide a cement reenforcement, that is strong, durable, simple and inexpensive in construction and well adapted to the purpose for which it is designed.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the accompanying drawings forming a part of the specification and in which like numerals are employed to designate like parts thrrmghout the same.

Figure 1 is a top plan view of the reinforcing network-in use,

Figure 2 is a detailed perspective of the cross section, and

Figure 3 is a detailed perspective of a joint or connection used in my invention.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates U-shaped channel irons which may be placed crossway of the road, in spaced relation to each other, and are so constructed, that they are a little shorter than the width of the road. As shown in the drawings, the U-shaped-channel bars 5 are provided with four V-shaped notches 6, which are adapted to receive V-s-haped angle irons represented by the numeral 7, said V-shaped angle irons being flush with the top of the U-shapcd channel bars. The U-shaped members 5 may be provided with openings 8, in order that the cement may have a better grip on the bars.

, In Figure 3 of the drawings, is illustrated the connection of the bars, that is used to join two sections of the V-shaped angle irons 7. One end of the V-shaped angle irons, is provided with a pressed seat 9, which is adapted to receive one end of the section that is to be joined thereto. In the. seat an opening 10 for the bolt 11 is provided so that a very good connection is made very close to the end, and does away with short pieces which would require more work.

As is clearly shown in Figure 1 of the drawings, the angle irons 7 are bolted at their intersections to the U-shaped members, by means of bolts 12. In use, the U-shaped members are laid crossways of the road, being a little shorter than the width of the road, and in spaced relation to each other. Long sections of the V-shaped angle irons are laid longitudinally in the road, in the V-shaped notches 6, which form a seat for said V-shaped members and are secured in place by means of bolts. The long members 13 are situated preferably near the center of the road. Near the ends of the U-shaped members, are shorter V-shaped members 14, and I have illustrated a form of construction which may be used, namely a short V- shaped member secured to two adjacent U- shaped members, and the U-shaped channel member on either side being less free at its end. In other words, there are live U- shaped channel members the two outer adjacent members being fastened and the intermediate member being left unfastened at its ends, however it is bolted to the longer channel irons 13 near its center.

I do not restrict myself to this specific arrangement, but have merely illustrated it as a satisfactory method, but will readily be seen that various arrangements could be used with equal satisfaction. Furthermore, I do not restrict myself as to the use of this reenforcement It will be seen that it would be as equally satisfactory if used in an asphaltum road. In addition, besides being used as a reenforcement for roadways, it could be used as a reenforcement for floors, walls, more or less vertical, as side walls of rooms, roofs, and the like, and which struoture will receive and sustain the greater portion of the burden of aconcentrated vertical load incident to its use inroadways walks, floors Water-proofing bridges, viaducts, etc.

It is to be understood that the form of my invention herewith shownanddescrihed is to be taken as a preferred embodiment of the same, and that various changes in'the shape, size and arrangement of parts may he resorted to, Without departing from the spirit of my invention or the scope of the sub-joined claim.

Having thus described my invention, I. claim A concrete reeniorcement comprising U- sha'ped channelirons, long sections of V shaped angle irons secured near the center of saidU-shaped channel irons, and short V-shaped members secured near the outer end of said U-shaped channel irons.

In testimony whereof I aflix my signature in presence of two Witnesses.

RAYMOND LARSON.
